Be it known that I, MATTHIAS KooH, of New York, in the county and Stateof New York, have invented a certain new and useful Improvement inSewing-Machines, of which the following is a specification.

I Will describe a sewing-machine embodying my improvement in detail, andthen point out the various novel features in the claims.

In the accompanying drawings, Figure lis a plan or top viewof themachine embodying my improvement, a certain support for the fabric beingbroken away to expose parts which otherwise would be concealed by it.Fig. 2 is a vertical section taken on the plane of the dotted line or.a', Fig. l, but made on a larger scale. Fig. 3 isa vertical sectiontaken on the plane of the dotted line y y, Fig. l.

Fig. S is a vertical section showing certainmechanism which may be used instead of that used in Fig. 5. Fig. 9 is aView of a piece of fabric quilted.

Similar letters of reference designate corre1 spondin g parts in all thefigures.

A designates the body or base-frame of the machine. It may be of anysuitable construction. Two long arms B are mounted upon the base-frame,one at each side thereof. The free ends of these arms support anintermediate bar or s.retcher B and carry the needles and theirappurtenances.

32 designates the needle-bar; B3, the needles, which may be of anysuitable number, arranged in any desired manner. The needle-bar reciprocates vertically. It is provided with a number of shanks or rods B4,extending upwardly through brackets B",secured to the bar or stretcherB. These rods B1 have secured to them collars, to which are pivotallyconnected links B, which are also pivotally connected to arms extendingfrom a rockshaft B, supported by the arms B. The rock-shaft BT isoscillated by means of rods B1", pivotally connected to arms extending55 from the rock-shaft and to disks aliixed to a rotary shaft B,supported by the arms B. The shaft B1 is shown as constituting thedriving-shaft of the machine, being provided with fast andloose pulleysB10 B11. `These pul- 6o leys are not, however, mounted directly upon theshaft, but upon a sleeve B12, arranged upon the shaft and adapted to beinterlocked therewith by means of a clutch, consisting of two parts bh2, one of which is affixed to the shaft and the other to the sleevebymeans of aspline, so that while it maybe moved longitudinally upon thesleeve,neither it nor the sleeve can have any independent rotation.Alever h3,

fulcrumed to a stationary part of the ma- 7o chine framing and having abifurcatc end provided with pins engaging with a groove in the hub ofthe part lf2 ot' the clutch, serves as a convenient means for adjustingthe part b2 of the clutch into or out of engagement with the part h ofthe clutch. The parts b b2 may be constructed in any approved manner toengage. For instance, one may be provided with a pin or pins and theother with a corresponding hole or holes in the opposite 8o I have notdeemed it necessary to not move into different positions or travel overthe fabric during the quilting.

The fabric to be quilted is sustained by a carriage C. This carriageconsists of two side pieces c and a number of intermediate bars orstretchers provided with two pairs of rollers c1125 c c1.. The fabric tobe quilted passes between one This carriage is roo pair of these rollersand then through the other pair. The rollers c"l c5, constituting onepair, are geared together by gear-wheels C8, and the rollers c c7,constituting the other pair, by gear-wheels 09, affixed to theirjournals. It will be seen that. one of each pair of rollers is furnishedwith a man-crank cw. The carriage C is supported by a carriage D. Thecarriage D consists of side pieces d d2 and intermediate stretchers cl3.The side pieces d of the carriage D may obviously be 5 connected belowthe body or base-frame of the machine by cross-pieces or stretchers, andthis is equally true of the side pieces d2 of the carriage D. It will beseen that one portion of the carriage D is at each side of thebase-frame of the machine. Each portion of the carriage D is providedwith a hooked tongue di, engaging with the adjacent side piece of thebase-frame. Each portion of the carriage D is also provided with twowheels or pulleys d5, which travel along ledges or tracks provided onthe sides of the base-frame. Each portion of the carriage is alsoprovided with wheels or pulleys d, bearing against the sides of thebase-frame. The carriage D travels in the direction of the length of thearms B.

The carriage D is provided with rollers C27, upon which are supportedthe side pieces c c2 of the carriage C. The carriage C will be movedwith the carriage D in the direction of the length of the arms B andtransversely to the length of theV needle-barpbut it can also have amotion independently of the carriage D in a direction transverse to thelength of the arms B and parallel with the length of the needle-bar.

It will be readily understood that by reason of the fact that the fabricis supported by the carriage C the fabric will be capable of movement inany desired direction in a horizontal plane beneath the needles.

I have now described the underlying principle of the machine. It is wellknown in the state of the art that the needles may be supported by acarriage, so as to travel over the fabric, instead of supporting thefabric upon a carriage, so as to have universal motion iu one plane. ltnow remains to describe the mechanism for imparting motion to the twocarriages and for imparting motion to the rollers with which thecarriage C is provided.

I will first explain the means for imparting motion to the carriage D.Each portion of the carriage D has affixed toit a toothed rack d8,extending iu the direction of the length of the arms B. TWith the racksds gear-wheels di engage. These gear-wheels d" are mounted upon a shaftD', supported by the base-frame of the machine. By rotating the shaft Din the desired manner the requisite movement of the carriage D will besecured. The shaft D has affixed to it a gear-wheel dw. En gaging withthe gear-wheel d10 is a rack du, which reciprocates horizontally and inthe direction of the length of thearms B. This rack serves as a meansfor transmitting motion to the shaft D. The rack d in effect constitutesa rod. Said rod is provided with pins CX12 (Z13, which coaet with tworotary pattern-cams D2 D3, aliixed to a rotary shaft D4. The shaft D4derives its motion through a large gear-wheel du, affixed to it andengaging with a small gear-wheel C115, which is mounted upon a shaft D5.The shaft D5 has a ratchet-wheel DG seeu red to it. A pawl CZG engageswith the ratchet-wheel and is carried by an oscillating arm looselymounted upon the shaft D5. This arm is oscillatedfby a rod d, worked byan eccentric d, affixed to a shaft D7. The shaft D7 receives anon-intermittent rotation by means of gear-wheels d d20, afiixed one toit and the other to the sleeve B12. The patternwheels D2 D3 are soshaped as to impart to the carriage D the requisite motion for anyparticular pattern. These pattern -wheels may be changed for others whendifferent patterns are desired.

l will now explain the mechanism for imparting motion to the carriage Cindependent-ly of the motion which is transmitted to the carriage D. Theside pieces c c2 are provided with toothed racks fr, which engage withpinionsE, affixed to a shaft E. This shaft is journaled in fixedportions of the machineframe and is provided with a long gear-wheel E2,rigidly secured to rotate with it. V-ith the gear-wheel Eza toothedrack-bar E3 engages. This rack-har reciprocates in a directiontransverse to the length of therarms B, and by reciprocating imparts arotary movement to the shaft E in one direction or the other, as may benecessary for the production of any desired pattern. Although the shaftE is supported in bearings arranged upon the fixed portion of themachine-frame, it is capable of a sliding movement in the direction ofits length, so that it may move with the carriage C in the direction ofthe length of the arms B. This is necessary in order that its pinions Emay maintain engagement with the racks r of the carriage. The pinionshave collars, which are fastened by set-screws or otherwise to theshaft. These pinions bear one against the outside of each of twoprojections with which the carriage D is provided. lVhen this carriage Dis moved, it transmits longitudinal movement to the shaft E by itsbearings against the pinions. The rack-bar E3 is operated by agear-wheel E, affixed to a shaft E5, mounted in bearings in the fixedportion of the machineframe. This gearwheel and its shaft rotatealways'in one direction.

E designates a pattern-wheel affixed to the shaft El", so as to rotatetherewith. The rackbar E3 is provided with two pins e3 e, which bearagainst the periphery of the patternwheel E, The patternwheel is thusenabled to reciprocatetherack-barand transmitmotion in reverse directiontransversely to the length of the arms B to the carriage C. The shaft E5derives motion from a shaft E7, the latter IOO IIO

being provided with a gear-wheel E8, which engages with the gear-wheelE4. The shaft F.7 is also provided with a bevel gear-wheel E9, thatengages with a bevel gear-wheel E10, affixed to the shaft D5. The shaftE7 thus derives motion from the shaft D5. As the shaft D5 derives motionfrom the ratchet DG and pawl d 15, it operates intermittingly. Itsintermittent motion being transmitted to the carriage C and carriage D,these carriages, as

well as the needles, operate with an intermit tent movement.

I will now describe a modification of 'the mechanism for producing theintermittent motion of the carriages C and D. This mechanism may besubstituted for the ratchet D" and pawl dw and the appurtenances ofthese parts. This modified mechanism is shown in Fig. 7. The shaft D7,instead of havin g an eccentric and eccentric-rod combined with it foroperating the pawl all, is provided with a bevel gear-wheel (1,25, whichmeshes into and drives a bevelwheel cl2, aiiixed to a shaft d2". Thisshaft also has affixed to it a bevel gear-wheel C128, which engages witha bevel gear-wheel d2, aiixed to a shaft ddl. The shaf t d3() hasaffixed to it an eccentric gear-wheel dgl. This engages with anothereccentric gear-wheel CW, affixed to a shaft di. The shaft cl3 hasaffixed toit a worm dit. This worm meshes into a worm-wheel d, affixedto the shaft D5. The eccentric gears (1516132 produce a substantiallyTintermittent motion of the shaft D5.

In Fig. 8 I have shown ameehanism exactly like that illustrated in Fig.7, excepting only that the gears c1316?? are not eccentric, but arecircular gears, and the shaft d33 has substituted for the worm dL athread (F6, which is horizontal throughout, but interrupted at one pointin its circumference, and an inclined segment of thread dal, which isopposite the interruption in the thread cl3". These threads dal dalengage with the teeth of the wormwheel 35 on the shaft D5. The thread dalocks the worm-wheel C135 against rotation, except when its interruptioncomes opposite said wheel. At this time the thread-segment Z3? engageswith the worin-wheel and moves it one tooth forward, after which thethread dfb' again engages with the worm-wheel and locks it.

I have now described the general characteristics of the machine. Toconduce to a clear understanding, I will add that the dotted line Fdesignates the fabric. The fabric is held during the sewing by thefecdrollers c4 c5 c I have also provided clips G for holding that edgeof the fabric which is nearest the needles. These clips may be readilyunderstood by reference to Fig. 6. They comprise, severally, bars g,mounted upon the side piece c2 of the carriage C and extending thenceupwardly and thence horizontally toward the needle-bar. Each bar g haspivotally connected to it a lever g. The lever g is above the horizontalportion of the bar g and is pivoted or fulcrumed between its ends.

The end which is the nearer to the needle-bar coacts with the adjacentend of the bar g to grip the edge of the fabric. The other end and thecorresponding extremity of the hori' zontal portion of the bar g haveinterposed between them a spring g2. This spring forces upwardly the endof the lever g,upon which it acts, and thereby causes the other end ofthe lever to grip the fabric. An eccentric g3 is affixed to a shaft g4,so as to be capable of actin g upon that arm or end of the lever uponwhich the spring g2 acts. By rotating the shaft g4 in one direction theeccentric g3 will be made to permit the spring g2 to act. By rotatingthe shaft g4 reversely the lever g may be oscillated so as to releasethe fabric. The shaft g4 is common to the eccentrics of all the clips Gand is provided with a handle g5, by which it may be convenientlyoscillated to operate all the clips.

The machine as described is intended for working the fancy pattern Fwhich is represented in Fig. 9, and not for performing the diagonallines of stitching F2 shown in said figure. During the quilting of thefancy pattern F the feed-rollers are motionless. After the fancy patternshall have been quilted upon such portion of the fabric as extendsbetween the pair of feed-rollers c4 c5 and `the other pair offeed-rollers cG cT one pair of feedrollers will be rotated to feed thisfinished portion of the fabric along and present another portion of thefabric between the two pairs of rollers, in order that it maybe quilted`with a continuation of `the same fancy pattern. This motion of thefeed-rollers may be produced by means of a hand-crank am. One of thefeed-rollers of each pair may be forced toward the other to maintain agrip upon the fabric. I have shown that I may combine with a pair offeed-rollers lneans whereby they maybe forced into contact with anydesired pressure. This may be understood by reference to Figs. 1 and 2.I have shown these means combined with the rollers c6 c7. These rollersare journaled in sliding boxes fitted in horizontally-extending grooves'or housings formed in the side pieces c c2 of the carriage C. Betweenthe boxes supporting the two rollers springs h are arranged. Thesesprings tend to force the rollers c6 away from the roller c7. The boxesof the rollers c have combined with them pins 7i', which are capable ofsliding lengthwise of the side pieces c c2 of the carriage. The outerends of these pins h impinge against eccentrics 7a2, mounted upon ashaft H. This shaft has aiiixed to one end a hand-crank h3. By rotatingthe shaft II the eccentrics h2 may be made to force the rollers c(against or toward the rollers c7 with any desired pressure.

I have shown the carriage Cas provided with rollers I I2. The fabric tobe quilted ICO IOS

IIO

may be wound upon one of these rollers and y which is illustrated asserving as a take-up roller, may be rotated from the roller c5 throughthe agency of a pulley t', affixed to the roller c5, a pulley t",affixed to said roller 12, and a belt i12. lt will be seen that theroller c4 has affixed to it at one end a bevel gearwheel c2, whichengages a bevel gear-wheel c, affixed to a shaft C22. The bevel-gear c21is secured to rotate with the shaft 022 by means of a spline or feather;but the bevelwheel 021 is capable of sliding lengthwise of the saidshaft c2? The bevel-wheel C21 is fitted in a bearing C23, which is afixture on the carriage C. This connection of the bevel gear-wheel 021with the shaft G22 affords provision for theV movement of the carriageC, and yet enables the shaft c22 to transmit rotary motion to the rollerc4. The shaft 022 has rigidly affixed to one end a bevel gear-Wheel 024,and the shaft is secured in a bearing c25 on one of the portions of thecarriage D. This gear-wheel and its shaft therefore move with thecarriages C and D in the direction of the length of the arms B, but donot partake of the movement of the carriage C in a direction transverseof the length of the arms B. The bevel-wheel c2* engages with a bevelgear-wheel 026, arranged upon a shaft J, which is journaled in the fixedportion of the machine-frame. The bevelwheel c26 is secured to rotatewith the shaft J by means of a spline or feather. The bevelwheel c2G issupported in a bearing in one of the portions of the carriage D, andhence when this carriage moves this bevel-wheel-is moved with itlengthwise of the shaft J. Obviously the shaft J, although stationary,is thus enabled to transmit rot-ary motion to the bevel- -wheel c2G andthence to the roller c4. The shaft J has affixed to one end a gear-wheelj', which engages with a gear-wheel j?. This wheel jg is mounted upon astud, which is supported in a swinging arm, the latter being looselysupported upon the shaft J. arm is similar to an arm K, (represented inFig. 3,) and hence its construction maybe readily understood byreference to the arm K and the appurtenances of the latter. Thegear-wheel t7'2 engages with a gear-wheel js, affixed to a shaft jl. Theobject of supporting the gearwheel t7'2 upon the arm is to enable it tobe substituted by a gear-wheel of larger or smaller size and stillpreserve the transmissiblity of motion from the gear-wheel .7'3 to thegearwheel j. The gear-wheel js has affixed to it a bevel-gear jf, whichengages with a bevel gear-wheelj, affixed to a shaftjT. The shaft j? hasaffixed to it a ratchet-wheel js. A pawlj coacts with thisratchet-wheel. The pawl ji is carried by a leverjlo, which is hungloosely upon the shaft j?. This lever is oscillated by means of a rod j,which is moved longitudinally in one direction by an eccentric or cam jmand in the other direction by a spring j. The cam or eccentric f2 isaffixed to and rofates with the shaft D?. The rod ju is connected to theleverj10 by means of a link jm.-

The link jl* has an adjustable connection ythreads of the needles.

This swinging y has affixed to it an arm fo.

with the lever by means of a bolt passing through said link and into aslot extending lengthwise of the lever. The rod j is not free at alltimes to move forward under the inuence of the springjl to follow thereceding periphery of the eccentric or cam jm, as itis controlled in theforward movement by a pattern-wheel jl. The pattern-wheel is of circularform, but has at one point in its periphery a long notch. The time ofthe rotaltionrof this pattern-wheel is such that the periphery of thepattern-wheelj15 the fancy pattern is being worked. By the time thenotched portion of the pattern-wheeljl5 comes opposite the pin 7'13 thefancy pattern has been completed. While the notched portion of thepattern-wheelis passing the pin js, and only .during this time, therodj11 is free to follow the eccentric j. During. this period no patternis being worked and the feed-rollers c4 c5 are automatically rotated`through the agency of. the pawlj9 and ratchetj8 to move the fabricforward far enough to present a new surface for the fancy pattern to beworked upon. lVhile the fabric is being thus fed to present a newsurface to be worked upon certain lines of straight stitchingparallelwith one edge` of the fabric are produced, which is preferable tocutting the These lines are not, however, intended to form any part ofthe pattern, but may be removed by trimming the fabric.

The pattern-wheeljl"l not only serves to effect the rotation of thefeed-rollers cJl c5 at the proper time, but `it has lthe additionalfunction of stopping'the rotation of the shaft D5, whereby the carriagesC and D are moved. I will now explain how this is done. The shaft A link,f2.1 connects this arm with a leverj, which is hung loosely upon theshaft D5. It will be readily understood that when the notched portion ofthe pattern-wheelj15 is opposite the pinj1B of the arm jui and theeccentric j and springj13 are permitted to reciprocate the rod j thelever f2 will simultaneously be oscillated, and its upper end, being inproximity to the pawl d1, will throw this pawl out of engagement withthe ratchet-wheel D6.

The rotation of the pattern-wheelj15 will now be explained. It isaffixed to ashaft f1. This shaft has affixed to it a gear-wheel ,742. Apinion f3 engages with the gear-wheeljfg. This pinion is affixed to ashaft, which has also affixed to it a ratchet-wheel f4. The

Icq

IXO

ratchet-wheelji4 is driven by a pawlf, aflixed to an arm, which isoscillated by an eccentric jm, which is affixed to the sleeve B12, thatis arranged upon the shaft B.

I will now describe a stop-motion. L designates a rock-shaft providedwith handles Z Zi whereby it may be conveniently rocked. The rod Z3 ispivotally connected to the handle Z at one end and supported at theother end in a guide Z4. This rod is provided with forks and constitutesa belt-shifter, Awhereby the main driving-belt may be carried from oneto the other of the fast and loose pulleys B10 B11.

I will now describe how the shaft L may be oseillated automatically tooperate the helt shifter rod Z3. The shaft L has affixed to it an armZH, which is shown as having a V- shaped upper portion that may beengaged by a pawl or dog Z5, pivot-ed at one end to a fixed portion ofthe maehine-frameaud drawn downwardly by a spring Z. This arm Z24 hasconnected to it a link Z7, which is also pivotally connected to a leverZS, which is fulerumed between its ends to the fixed portion of themachine-frame and is shown as having a bent or offset portion at thelower end. The shaft E5 is shown as having afiixed to it a disk or wheelZ, provided with a toe or projection similar to a ratchet-tooth. lVhenthe shaft nearly completes a rotation, the projectionfrom the disk Z5will oscillate the lever ZR, so as to cause it to oscillate the arm Z2*toward the spring l", actuating the pawl Finally the projection of thedisk Z swings the arm Z2* so far over that the V-shaped under side ofthe pawl Z5 acts in conjunction with the V- shaped upper end of the saidarm Z24 to throw the arm Z24 quickly over toward the spring ZG. Thiswill effect the oscillation or rocking of the shaft L to such a degreeas to cause the shifting of the belt from one to the other of the fastand loose pulleys B10 B1'. This oecurs at the time that the fancypattern is conipleted on any one portion of the fabric, and the fabricin consequence thereof requires to be removed to present a new surface.The pawl Z5 of course is provided with a stop-such, for instance, as apin ZlO-to prevent it from being pulled too far downwardly by the springZG when not supported by the arm Z24.

When the fabric is fed so as to cause the stitching of the straightlines near one edge of the fabric, the mechanism for imparting motion tothe carriages is rendered inoperative. This is done by loosening certaingears,

as will hereinafter be explained.

I will now describe how the machine may be disorganized for quilting afa'ney pattern, such as the pattern F', Fig. 9, and organized to quiltdiagonal lines F2, Fig. f). The gear- Wheel (Zw is disengaged from theshaft D5 in the present instance by loosening a screw, which secures itshub to the shaft. This change prevents the shaft D5 from transmittingmotion to the carriage D through the rack-bar d, gearwheel CZO, shaftD,and gearwheel d. The gear-wheel di" is new loosened by disengaging thescrew which secures it to the shaft D. his change leaves the shaft Dfree to rotate under the control of other mechanism. The pattern-wheelj,when'adj usted so that its notched portion will be opposite the pinjls,is disengaged from the mechanism which imparts motion to it by looseningthe eccentricj40 from the sleeve B12, which is arranged upon the shaftB9. This may he done by loosening the screw, which in the presentinstance passes through the hub ol' the said eccentric and secures it tosaid sleeve. Thus the pattern-Wheel j15 will be made to remain idle,with its notched portion opposite the pin js. The eccentric j and thespring j will therefore be left free to effect the rotation of thefeed-rollers c4 c5. The gear-Wheel E8 is also disengaged from the shaftET inthe present instance by slackeningascrew which passes through thehub of said gear-wheel and impinges upon the said shaft. This changeprevents the shaft D?l from transmitting motion to the carriage Cthrough the pattern-wheel E, rack-bar E3, shaft E', pinions E, and theracks fr, arranged upon said carriage. For the diagonal lilies ofstitching the carriage C has no motion imparted to it independently ofthe carriage D, bntis, in effect, apart'of the carriage D for the time.The carriage D is now operated by a different mechanism, deriving motionfrom the shaft D5. In this mechanism there is a gearwheel k, affixed toone end of the shaft D5 and engaging with a gear-wheel Zt', which issupported upon a stud projecting from the arm K. The arm K is hung atthe upper end pon the shaft D5. Its stud, which supports the gear-wheelZu', iits in a slot extending lengthwise of said arm. The stud maytherefore be adjusted lengthwise of said arm and toward and from thegear-wheel Zr.. The arm K at the lower end has in it an arc-shaped IOOslot, which is concentric with the axis of the this arc-shaped slot andserves to secure the arm K in different positions. The gear-Wheel kengages with a gear-wheel 7,12. The object of the arm K is to providefor the substitution of a change-gear, or, in other words, a gear of adilferent size, instead of the gear la', to vary the speed of themotion, which will be transmitted to the gear-wheel 702. The gear-wheelZr? is mounted loosely upon the shaft D4. A pattern-wheel or cani 7e3 isalso loosely mounted uponthis shaft. This pattern-wheel and thegear-wheel Ztaale secured upon a sleeve common to both, or otherwisesecured to rotate in unison independently of the shaft D1. Thepattern-wheel 7f3 operates in connection with two pins Ztl, extendingacross opposite points in its periphery from a rod L5. The pattern-wheel7e3 thus imparts a reciprocating motion to the rod Zt. The rod Z5 isconstructed at one end to form a rackbar, which engages with agear-wheel k6,

affixed to a shaft k7. The shaft 70T has also affixed to it a gear-Wheel7c8. This gear- Wheel 7a8 engages with a gear-wheel 7c". The gear-Wheel7c is affixed to a shaft 71:10, having secured to it at one end abeveled gearwheel 7CH. The shaft 7&9 is supported in a movable bracket7tlg. This bracket issecu red to a fixed portion of the machine-frame bymeans of screws or bolts passing through slots extending transversely tothe length of said shaft. This enables cliange-gearrto be employed, asthe gear 7d) may be shifted and replaced by another upon the shaft 7am.The bevel-Wheel 7c engages with a bevel-gear 7&3, affixed to aV shaft7&4." Vhen the bracket 7912 is adjusted into a different position, thebevel- Wheel 7&3 may be adjusted lengthwise of the shaft 7c and securedin a different position.

The shaft 7c has affixed to one end a bevel-` wheel 7&5, which engageswith a bevel-Wheel 7cm, affixed to the shaft D. As the shaft D transmitsmotion to the carriage D through the gear-wheel d, with which said shaftis provided, and the racks C78, with which said carriage is provided, itis obvious Ythat the shaft D5 now transmitsaY reciprocating inotion tothe carriage D under the control of the pattern-Wheel or cani 7c3.. Y'

When the machineris organized as just described, the carriage Dand thecarriage@ with it will beinoved in the direction of the length of thearms BY under control of the patternwheel 7c3, andthe feed-rollers c4cwill simultaneously be rotated through the agency of the pawl j" andratcliet-Wheeljs. The result Yof the combined movements imparted to thefabric by and the movement of the carriages in the direction of thelength of the arms B Willbe an oblique movement of the fabric beneaththe needles. Oblique lines of stitching, such as those I?? in Fig. 9,Will therefore be sewed or quilted upon the fabric.
